JOHN Y. PARKE, OF PHILADELPHIA, PENNSYLVANIA.

GAS-BURNER.

To all whom it may concern:

Be it known that 1, JOHN Y. PARKE, a citizen of the United States, and aresident of the city of Philadelphia, State of Pennsylvania, haveinvented certain new and useful Improvements in Gas-Burners, of whichthe following is a full, clear, and complete disclosure.

T he object of my invention is to provide such a construction in valvesfor gas burners and other conduits where a gas or fluid is conveyed fromone place to another, that said valve will besimple and inexpensive tomanufacture, efficient in operation and very durable in wearingqualities.

Briefly, my invention comprises a fluid conduit, within which is locateda loose valve member which is adapted to be unseated when a suitable keyis turned to allow the passage of the gas or other fluid, said valvemember being preferably held in position by means of a spring member.

F or a full, clear and exact description of one embodiment of myimprovements reference may be had to the following specification and tothe accompanying drawing forming a part thereof, in which Figure 1 is aside elevation partly in section of one embodiment of my improved valve;Fig. 2 is a similar enlarged view thereof also showing certain partsthereof in section; and Fig. 3 is a detail view of the key, showing thecam for operating the valve.

eferring to the drawing the numeral 1 indicates a casing of a gas et orother fluid conduit and 2 a key for operating my improved valve, saidkey rotatably mounted in the casing 1 in any suitable manner. Thepassage 3 within the casing 1 is expanded into an enlarged chamber 4 thecorner between the said passage and chamber being beveled as indicatedat 5 to form a valveseat. Upon this valve-seat is placed a sphericalbody or ball 6, accurately shaped, and preferably of steel or otherdurable material. A plunger or follower 7 is adapted to rest upon saidball 6 and is yieldably held in position by means of a coiled spring 8,said coiled spring being held within the chamber 4 in any suitablemanner as in this instance by abutting against the lower end of the lavatip 9. It is obvious that the plunger 7 may be omitted and the spring 8bear directly on the ball, but I Specification of Letters Patent.

prefer to use the plunger inasmuch as the end thereof gives a surfacehaving a sliding contact with the ball. As means for dis placing saidball or valve member 6 from its seat I provide a pin 10 which passesthrough an opening 11 in the casing 1, the inner end of which is adaptedto engage the ball 6. The outer end of said pin 10 is adapted to engagewith a suitable cam 12 in the form of an inclined surface or groovecarried by the key 2.

In operation it will be seen that when the key 2 is rotated upon itsaxis the cam 12 will force the pin 10 inward and thereby displace theball 6 against the yielding pressure of the plunger 7 which will allowsufficient space between the valve-seat 5 and the ball 6 to permit thegas or other fluid to easily pass. When the key is rotated in theopposite direction from that just described the ball 6 will be reseatedon the valve-seat and the passage 3 closed.

My improved form of valve forms a fixture or burner for gas jets whichis especially adapted to gases which give out a great amount of heat,such as acetylene.

Having thus described my invention it is obvious that changes may bemade in the form, proportion and arrangement of parts and mechanicalequivalents may be substituted without departing from the spirit andscope of my invention, but

What I claim and desire to protect by Letters Patent of the UnitedStates is 1. A fluid supply conduit comprising a cas ing provided with astraight passage for fluid, having one portion of larger bore than theremaining portion, a valve seat at the junction of the said portions, aball of larger diameter than the bore of the smaller portion of the saidpassage, loosely seated in the valve seat, a rod slidably mounted nearthe part of the casing surrounding the passage of larger bore, and a keyrotatably mounted on the casing and provided with a flange substantiallyat right angles to the said rod and having a cam surface which engagesthe outer end of the rod for reciprocating the said rod.

A fluid supply conduit comprising a casing provided with a straightpassage for fluid, having one portion of larger bore than the remainingportion, a valve seat at the junction of the said portions, aball oflarger diameter than the bore of the smaller portion of the saidpassage, loosely" seated on surfaee which engages the outer end of the10 the valve seat, a spring located in the larger rod for reciprocatingthe said rod.
